During the past week I attempted to order service with AT&T Wireless. When their credit department was unable to access my credit report I was directed to contact Equifax. I contacted Equifax and determined that my telephone numbers needed updating and this would be completed in 72 hours. When I called AT&T Wireless back, 4 days later the representative I spoke with, Michelle Seymour, placed me on hold to check with their credit department. She stated they were trying to call me and placed me on hold. When she came back on the line I asked how they could call me when I'm currently on the telephone with her. She did not answer this question directly and continued to state that they must contact me. When I asked to speak to a supervisor she refused. When I pressed the issue of a customer complaint she provided the following address, P.O. Box 755, Atwater, CA 95301. After two 30 minute calls and the company's refusal to connect me with a supervisor. I've determined that AT&T is not a company I will do business with.
